Abstract
At the end of the last century, a far-sighted 'working party' held in Sydney, Australia addressed the clinicopathological issues related to gastric inflammatory diseases. A few years later, an international conference held in Houston, Texas, USA critically updated the seminal Sydney classification. In line with these initiatives, Kyoto Global Consensus Report, flanked by the Maastricht-Florence conferences, added new clinical evidence to the gastritis clinicopathological puzzle.The most relevant topics related to the gastric inflammatory diseases have been addressed by the Real-world Gastritis Initiative (RE.GA.IN.), from disease definitions to the clinical diagnosis and prognosis. This paper reports the conclusions of the RE.GA.IN. consensus process, which culminated in Venice in November 2022 after more than 8 months of intense global scientific deliberations. A forum of gastritis scholars from five continents participated in the multidisciplinary RE.GA.IN. consensus. After lively debates on the most controversial aspects of the gastritis spectrum, the RE.GA.IN. Faculty amalgamated complementary knowledge to distil patient-centred, evidence-based statements to assist health professionals in their real-world clinical practice. The sections of this report focus on: the epidemiology of gastritis; Helicobacter pylori as dominant aetiology of environmental gastritis and as the most important determinant of the gastric oncogenetic field; the evolving knowledge on gastric autoimmunity; the clinicopathological relevance of gastric microbiota; the new diagnostic horizons of endoscopy; and the clinical priority of histologically reporting gastritis in terms of staging. The ultimate goal of RE.GA.IN. was and remains the promotion of further improvement in the clinical management of patients with gastritis.

Abstract
Drugs are widely used to treat different diseases in modern medicine, but they are often associated with adverse events. Those located in the gastrointestinal tract are common and often mild, but they can be serious or life-threatening and determine the continuation of treatment. The stomach is often affected not only by drugs taken orally but also by those administered parenterally. Here, we review the mechanisms of damage, risk factors and specific endoscopic, histopathological and clinical features of those drugs more often involved in gastric damage, namely NSAIDs, aspirin, anticoagulants, glucocorticosteroids, anticancer drugs, oral iron preparations and proton pump inhibitors. NSAID- and aspirin-associated forms of gastric damage are widely studied and have specific features, although they are often hidden by the coexistence of Helicobacter pylori infection. However, the damaging effect of anticoagulants and corticosteroids or oral iron therapy on the gastric mucosa is controversial. At the same time, the increased use of new antineoplastic drugs, such as checkpoint inhibitors, has opened up a new area of gastrointestinal damage that will be seen more frequently in the near future. We conclude that there is a need to expand and understand drug-induced gastrointestinal damage to prevent and recognize drug-associated gastropathy in a timely manner.

Abstract
We here draw attention to a practical issue: the approach to certain unusual gastric ulcers with haemorrhage- or perforation-induced complications. This category of ulcers, i.e., giant (over 2–3 cm) and multiple ulcers, is rarely encountered. We discuss the circumstances determining the occurrence of such lesions, their diverse aetiology and pathogenesis, their common manifestations, and the severity of their evolution. Some of the lesions are benign (chronic or acute ulcers), whereas others are neoplastic: carcinoma, stromal tumours, and lymphomas. In gastric ulcers, the characteristics of this particular and rare category of lesions strictly places them in the surgical field, requiring primary surgical intention. Conservative treatments are not effective in such cases, and preoperative biopsies are not appropriate for emergency interventions. Whether these unusual ulcers are benign or malign, they need to be surgically removed.

Abstract
BACKGROUND Helicobacter-negative gastritis is diagnosed when no organisms are detected in a gastric mucosa with typical features of Helicobacter gastritis (Hp-gastritis). If Helicobacter-negative gastritis consisted mostly of 'missed' Helicobacter infections, its prevalence should represent a constant percentage of these infections in a population, and their clinico-epidemiological features would overlap. AIM To compare the epidemiologic patterns of Hp-positive and Hp-negative gastritis. METHODS From a pathology database, we extracted demographic, clinical and histopathological data from patients with gastric biopsies (1.2008-12.2013). We allocated patients to high (≥12%) and low (≤6%) H. pylori prevalence regions defined by ZIP code-based data. The prevalence of H. pylori-positive and -negative gastritis by sex, age and state were expressed as a per cent of the total study population stratified accordingly. RESULTS Of 895 323 patients, 10.6% had Hp-gastritis and 1.5% Helicobacter-negative gastritis. Hp-gastritis, but not Helicobacter-negative gastritis, was more common in males than females (OR 1.17, 95% CI: 1.16-1.19). While Hp-gastritis was more prevalent in high than in low-prevalence areas (OR 3.65, 95% CI: 3.57-3.74), Helicobacter-negative gastritis was only minimally affected by the underlying H. pylori prevalence (1.7% vs. 1.5%). The age-specific prevalence of Hp-gastritis peaked in the 4th to 5th decades; Helicobacter-negative gastritis exhibited a low and relatively flat pattern. The geographic distribution of H. pylori-positive and -negative gastritis showed no significant correlation. Intestinal metaplasia was found in 13.0% of patients with Hp-gastritis and in 6.1% of those with Helicobacter-negative gastritis (OR 0.43, 95% CI: 0.40-0.47). CONCLUSION These data suggest that Helicobacter-negative gastritis is, in the vast majority of cases, a nosologically and epidemiologically distinct entity that deserves further investigation.

Abstract
In keeping with the stated goal of providing the surgical pathologist with tools to recognize abnormalities of the gastrointestinal (GI) tract due to drugs (AGIDS), in part II of this review we embark in a more organ-based description of AGIDS. Adequate space is given to the numerous adverse gastrointestinal effects of nonsteroidal anti-inflammatory drugs. Pill esophagitis, esophagitis dissecans, proton pump inhibitors’ effects, diaphragm disease, and the recently described effects of drugs such as olmesartan, mycophenolate, and of compounds such as yttrium-90 are highlighted among several others. The inclusion of drug effects in the differential diagnosis of “conventional” diseases (such as gastric antral vascular ectasia, graft-versus-host disease, ischemic colitis, acute colitis, collagenous enteritis, inflammatory bowel disease) is underscored to avoid sometimes significant diagnostic pitfalls. We reiterate the message of the necessary collaboration between pathologist and clinician in the recognition of these entities to provide the best patient care.

Abstract
BACKGROUND The histopathologic characteristics of the antral erosions, and a comparison with samples systematically collected from the background antral mucosa, have not been studied previously. Similarly, unknown is the association of these features with suspected etiological factors and chronicity of erosion. MATERIAL AND METHODS We studied 117 patients with gastric erosions in the absence of peptic ulcer disease. With 28 patients available for a follow-up 19 years later, sites of erosions and background mucosa were biopsied and histopathology of both independently assessed at both visits. Helicobacter pylori status was examined from the biopsies taken in the initial and follow-up gastroscopies. Only subjects originally displaying antral erosions were included. The presence of Herpes simplex virus (HSV) antibodies was analyzed and use of nonsteroidal anti-inflammatory drug (NSAID) was inquired. RESULTS Initially, the inflammation was more active in the region of erosions than elsewhere in antral mucosa. More active inflammation in the erosion was associated with HSV seropositivity, Helicobacter pylori infection, and the recent use of NSAIDs. In the follow-up visit, antral erosions were present in 38% (3/8) of Helicobacter pylori negatives and in 35% (7/20) of positives (p = ns). The Helicobacter pylori positive subjects with chronic or recurrent erosions had initially higher scores of neutrophils compared to subjects with nonrecurrent or nonchronic erosions (2.7 ± 0.5 vs 1.2 ± 1.0; p = .002). CONCLUSIONS Focally enhanced inflammation is characteristic for gastric erosions. This focal inflammation was associated with HSV seropositivity or NSAID use suggesting that such inflammation may be important in the pathogenesis of gastric antral erosions. Highly active inflammation in the erosions associates with their chronicity.

Abstract
Pseudoneoplastic regeneration has become an important differential diagnosis to gastric carcinoma. Increasing use of acetylsalicylic acid (ASA) and non-steroidal anti-inflammatory drugs (NSAIDs) appears to be related to this entity. In recent years knowledge of pseudoneoplastic regeneration has continuously improved and the proportion of this designation among cases sent to our institute for second opinion decreased from more than 50% in 2000 to approximately 10% today. In diagnostically difficult cases the gastritis status may help: the majority of patients with gastric carcinoma show either active or treated Helicobacter gastritis, whereas individuals with pseudocarcinomatous regeneration often show chemical reactive gastritis (reactive gastropathy). Gastric ulcers should always be followed-up during the healing phase. A second opinion may confirm the differential diagnosis.

Abstract
BACKGROUND Irritable bowel syndrome (IBS) and functional dyspepsia (FD) are common functional disorders without defined pathology. Mast cells and eosinophils interact with T lymphocytes and may alter enteric nerve and smooth muscle function. AIM To examine mast cell, eosinophil and intraepithelial lymphocyte populations in duodenal biopsies of subjects with IBS and FD. METHODS A random sample of an adult Swedish population (n = 1001; mean age 54 years; 51% female) underwent upper endoscopy and biopsy; 51 cases with FD and 41 cases with IBS were compared with 48 randomly selected controls. Eosinophils were identified by light microscopy; mast cells by immunocytochemistry (CD117). Intraepithelial lymphocytes were counted per 100 enterocytes. Cell counts were quantified by counting the number per high power field (HPF) in 5HPFs in the bulb (D1) and second part of duodenum (D2), summed over 5HPFs at each site. RESULTS Cases and controls showed similar demographics. Compared to controls, IELs in IBS-constipation were significantly increased (P = 0.005). Mast cells were significantly increased in IBS in D2 (P < 0.001), while eosinophils were significantly increased in FD in D1 and D2 (P < 0.001). CONCLUSION Duodenal mast cell hyperplasia is linked to IBS and eosinophilia to FD, and duodenal biopsy may identify subsets of these disorders.

Abstract
OBJECTIVE Serological biomarkers can be used for non-invasive diagnosis of gastritis and atrophic gastritis. The aim of this study was to compare the validity of serum levels of pepsinogen I (PGI) and II (PGII), gastrin-17 (G-17) and Helicobacter pylori antibodies (Hpab) with that of the gold standard histology for diagnosis of atrophic gastritis in a population sample from Northern Sweden. MATERIAL AND METHODS In all, 1000 subjects underwent endoscopies with biopsies. Serum biomarkers were available in 976 subjects for independent diagnosis of gastric mucosal status using a predetermined diagnostic algorithm. RESULTS Overall agreement between histology and serological biomarkers in diagnosing corpus atrophy was 96% (CI 95%: 95-97%). Sensitivity and specificity of markers for atrophic gastritis were 71% (CI 68-74%) and 98% (CI 97-99%) respectively, corresponding to 69% (CI 95%: 66-72%) and 98% (95% CI 97-99%) positive and negative predictive values. The positive likelihood ratio was 35.5 (95% CI: 35.0-36.0%). In subgroups with normal stomachs, H. pylori non-atrophic gastritis and H. pylori-negative gastritis by histology, the prevalence of corpus atrophy diagnosed with the biomarkers was 0.8% and 4.9%, respectively. In total, 6.6% of subjects in the study population had corpus atrophy according to the serological biomarkers. CONCLUSIONS. Serological biomarkers show a high degree of accuracy as a non-invasive method to diagnose corpus atrophy, which is common in the general population.

Abstract
OBJECTIVE Evaluation of gastrointestinal blood flow is important. However, a non-invasive measurement method has not yet been established. The aim of this study was to compare measurement of normal gastric mucosal blood flow by advanced dynamic flow (ADF) flash echo imaging (FEI) with intravenous Levovist with measurement by laser Doppler flowmetry (LDF) to clarify the usefulness of ADF-FEI and thereby consider its feasibility as a non-invasive gastric mucosal blood flow measurement method. MATERIAL AND METHODS Measurements were obtained in 25 beagle dogs (8-month-old males, body-weight, 10.6+/-1.3 kg, mean+/-SD). After insertion of a gastrointestinal endoscope, gastric mucosal blood flow at the greater curvature of the corpus was measured by LDF, and images of gastric mucosal blood flow were obtained by ADF-FEI (frequency; 4.7 MHz) with intravenous injection of Levovist (30 mg/kg). ADF-FEI images were transferred to a personal computer. A region of interest was set on the mucosa of the greater curvature of the corpus, and a time intensity curve (TIC) was plotted from the measured echo intensities. The area under the curve (AUC) calculated from the TIC and the median flow determined by LDF were analyzed and compared. RESULTS Evaluation of normal gastric mucosal blood flow by ADF-FEI was possible in all animals. There was a strong, significant correlation between gastric mucosal blood flow measured by LDF and the AUC obtained by ADF-FEI (r=0.869, p<0.0001). CONCLUSIONS Gastric mucosal blood flow can be accurately measured by ADF-FEI with intravenous Levovist injection.

Abstract
Reactive or chemical gastropathy is the constellation of endoscopic and histological changes caused by chemical injury to the gastric mucosa. Its diagnosis rests on the histopathological demonstration of nonspecific elementary lesions that may occur simultaneously or separately in different degrees and various proportions. These lesions include foveolar hyperplasia, interfoveolar smooth muscle fibers, erosions, edema, and hyperemia, in the absence of significant inflammation. Their respective occurrence in a set of gastric biopsies can be placed on a spectrum of diagnostic certainty that is never absolute because each of such changes can and does occur in other conditions. Although a correlation between histological evidence of chemical gastropathy and clinical manifestations, particularly risk of bleeding, is yet to be documented, reporting the suspicion of drug-induced gastric damage may help clinicians to identify patients that might benefit from change, reduction, or discontinuation of certain medications.

Abstract
The authors' aim in this study was to explore the prevalence, symptomatology, and risk factors for peptic ulcer in a general adult population. Between December 1998 and June 2001, the authors surveyed a random sample (n=3,000) of the adult population (n=21,610) in two communities in northern Sweden using a validated questionnaire, the Abdominal Symptom Questionnaire (response rate=74%). A subsample (n=1,001) of the responders was randomly invited to undergo esophagogastroduodenoscopy and symptom assessment (response rate=73%). The prevalence of peptic ulcer was 4.1% (20 gastric ulcers and 21 duodenal ulcers). Nausea and gastroesophageal reflux were significant predictors of peptic ulcer disease, but epigastric pain/discomfort was not. Six persons with gastric ulcer and two persons with duodenal ulcer were asymptomatic. Eight subjects with duodenal ulcer (38%) lacked evidence of current Helicobacter pylori infection. Five (25%) of the gastric ulcers and four (19%) of the duodenal ulcers were idiopathic (no use of aspirin or nonsteroidal antiinflammatory drugs, no H. pylori infection). Smoking, aspirin use, and obesity were risk factors for gastric ulcer; smoking, low-dose (<or=160 mg) aspirin use, and H. pylori infection were risk factors for duodenal ulcer. Peptic ulcer disease often coexists with atypical symptoms or no symptoms at all, and idiopathic duodenal ulcer may be more common than anticipated.

Abstract
The pain-relief properties of NSAID/ASA preparations have been known for a long time. In particular, the gastrointestinal tract shows side effects such as: erosion, ulceration, and even perforation. In the upper gastrointestinal tract, our group has shown that a correct histological diagnosis of NSAID/ASA induced lesions can be made in a high percentage of cases on the basis of recognition of ischemic necrosis. NSAID/ASA induced lesions are less commonly found in the lower gastrointestinal tract. We could also demonstrate a correct histological diagnosis of NSAID-colonopathy on the basis of finding ischemic necrosis. Besides the known complications, another typical complication is diaphragm-like stenosis, which must not be mistaken for tumor stenosis. The differential diagnosis of NSAID-colonopathy includes ischemic colitis, which cannot be distinguished histologically if the exact endoscopic description is not available. Sometimes NSAID/ASA induced lesions are misdiagnosed as Crohn's disease due to the focal character of the lesions. Since all of our analyses are retrospective, the criteria developed by our group should be checked prospectively.

Abstract
AIM: To investigate whether NSAIDs/ASA lesions in the colon can histologically be diagnosed on the basis of ischemic necrosis similar to biopsy-based diagnosis of NSAIDs/ASA-induced erosions and ulcers of the stomach.
METHODS: In the period between 1997 and 2002, we investigated biopsy materials obtained from 611 patients (415 women, 196 men, average age 60.5 years) with endoscopic focal erosions, ulcerations, strictures or diaphr-agms in the colon. In the biopsies obtained from these lesions, we always established the suspected diagnosis of NSAID-induced lesions whenever necroses of the ischemic type were found. Together with the histological report, we enclosed a questionnaire to investigate the use of medication. The data provided by the questionnaire were then correlated with the endoscopic findings, the location, number and nature of the lesions, and the histological findings.
RESULTS: At the time of their colonoscopy, 86.1% of the patients had indeed been taking NSAID/ASA medication for years (43.9%) or months (29.5%). The most common indication for the use of these drugs was pain (64.3%), and the most common indication for colonoscopy was bleeding (55.5%). Endoscopic inspection revealed multiple erosions and/or ulcers in 60.6%, strictures in 15.8%, and diaphragms in 3.0% of the patients. The lesions were located mainly in the right colon including the transverse colon (79.9%). A separate analysis of age and sex distribution, endoscopic and histological findings for NSAIDs alone, ASA alone, combined NSAID/ASA, and for patients denying the use of such drugs, revealed no significant differences among the groups.
CONCLUSION: This uncontrolled retrospective study based on the histological finding of an ischemic necrosis shows that the histologically suspected diagnosis of NSAID-induced lesions in the colon is often correct. The true diagnostic validity of this finding and the differentiation from ischemic colitis should, however, be investigated in a prospective controlled study.

Abstract
BACKGROUND Hypoxia is a cause of gastric mucosal damage induced by nonsteroidal anti-inflammatory drugs (NSAIDs). The expression of hypoxia inducible factor-1alpha (HIF-1alpha) reflects the status of tissue ischaemia. AIM To investigate the effect of NSAID administration on the expression of HIF-1alpha in human gastric mucosa. METHODS We employed 71 patients including 14 with NSAID administration. The HIF-1alpha expression was estimated by immunohistochemistry using monoclonal antibody (H1alpha67) and raised antiserum (HI-3). Vascular endothelial growth factor expression was also examined by immunohistochemistry. HI-3 recognized hypoxia-induced protein in HeLa cells. RESULTS In human gastric mucosa, HIF-1alpha was mainly expressed in the nuclei of the surface epithelial cells and in the neck zone both by use of HI-3 and of H1alpha67. The expression of vascular endothelial growth factor correlated well with that of HIF-1alpha. The level of HIF-1alpha in the surface epithelium was significantly higher in patients with administration of NSAIDs than those without NSAID use (P < 0.001) both in the gastric corpus and antrum. Helicobacter pylori infection did not affected the levels of HIF-1alpha. Long-term administration of rebamipide reduced the level of HIF-1alpha. CONCLUSION HIF-1alpha expression is a new biological marker of ischaemia especially in NSAID-related gastric lesions.
